VALVE LIFTER.

To all whom it may concern Be it known that I, ARCHIE TAYLOR, a citi-Zen of the United States, residing at Scotch Plains, in the county ofUnion and State of New Jersey, have invented certain new and usefulImprovements in Valve Lifters, of which the following is aspecification.

This invention relates to valve tools or implements for internalcombustion engines or the like and more particularly to a novel andimproved device for manipulating and removing valve springs withfacility and ease.

The primary object of my invention is the provision of a hand operatedimplement or tool particularly adapted for use in compressing heavysprings such as are used in connection with valves for internalcombustion engines wherein said springs may be compressed and the cotterpin removed in such instances where it is impossible to manipulate thespring with the common ordinary tool.

Another and very important object of my invention is the provision of avalve manipulating tool of the character above specified having anadjustable fulcrum for engaging the flanged portion of the cylindercasing so that the lever arm of the tool may properly engage the valvespring to be raised when removing the same from the valve stem.

Another object of my invention is the provision of a lever operatedvalve spring removing tool, which is extremely simple in construction,highly efficient in operation and use, strong, durable, practical,easily assembled and otherwise capable of being manufactured at anextremely low cost. whereby its commercial possibilities are greatlyenhanced. V

I attain the above objects and others which will become apparent as thedescription proceeds when taken in connection with the drawings andwherein:

Figure 1 is a part sectional side view of the valve spring showing thedevice in its preferred form as the spring is being raised orcompressed.

Figure 2 is a side view of the tool.

Figure 3 is a plan.

Figure 4 is a front view.

Referring now to the drawings wherein like reference charactersdesignate corresponding parts throughout the several views, 5 designatesthe cylinder casting of the engine, 6 the valve stem, 7 the usual valvespring. 8 designates the usual washer held in place by the key or cotterpin 9 passing through the valve stem, which pin or key must be removedas the valve spring is raised on the stem.

In order to accomplish the above function, I have provided a bent leverconsisting of a shank lOhaving a handle 11 atone end thereof said leverbeing bent downwardly as at 12 and terminating in a fork 13, the arms14, 15 of which are adapted to engage the bottom of the spring to becompressed or lifted. Pivotally mounted between the arms 14, 15, I haveprovided a block 16. The said block is pivotally mounted as at 17some-what re moved from the ends of the arms 14, 15 and is internallythreaded to receive the vertically adjustable screw 18 passingtherethrough as clearly shown by the drawings.

Rigidly mounted and attached to the lower end of the screw 18, I haveprovided a forked fulcrum or gripping element designated in its entiretyby numeral 19, the arms 20, 21 of said element being notched or serratedas at 22 so as to grip the flanged portion of the cylinder casing, itbeing observed that the opposite end of the said element 19 is bevelledto its edge 23 so as to lie perfectly fiat with the wall of the casingduring the gripping thereof as the lever is manipulated.

By reason of this construction it will be readily seen that as the screw18 and the fulcrum 19 carried thereby, are adjusted to accommodate thedesired spring to be raised that by simply depressing the lever 10, thespring 7 may be compressed and the pin or key removed in the well knownmanner without danger to the operator. Of course a downward thrust onthe fulcrum 19 will securely maintain the same in position and withoutdanger of slipping and at the same time, the lever 10 being pivoted onthe block 16 permits of the raising of the arms 14 and 15 engaging thespring to be lifted.

While I have illustrated and described my invention with some degree ofparticularity, I realize that in practice various alterations thereinmay be made. I therefore reserve the right and privilege of changing theform of the details of construction or otherwise altering thearrangement of the correlated parts without departing from the spirit ofthe invention or the scope of the appended claims.

Having thus described my invention what I claim as new and desire tosecure by United States Letters Patent is l. A valve spring liftercomprisin a lever, a fork formed at one end thereo a carried by thelower end of the screw to engage the flange of a cylinder.

2. A valve spring lifter comprising a lever,

a fork formed at one end thereof, a pivotally mounted, internallythreaded block carried by the forked end of the lever, a screwadjustable in said block, an angular fulcrum element-carried bythescrew,one end of said fulcrum element being serrated and the opposite endbevelled so as to engage the flange and side wall respectively of acylinder cas 20 ing as the lever'is manipulated.

In testimony whereof I affix my signature.
